RODRIGUES, Bruna Fragoso; OLIVEIRA, Clarissa Tochetto de; MOREIRA JUNIOR, Fernando de Jesus  and  DIAS, Ana Cristina Garcia. Construction and validation of the ADHD knowledge scale. Rev. Subj. [online]. 2024, vol.24, n.1, e12975.  Epub Mar 09, 2026. ISSN 2359-0769.  https://doi.org/10.5020/23590777.rs.v24i1.e12975.

The objective of this study was to present the validity construction and evidence of a scale that assesses knowledge about Attention Deficit/Hyperactivity Disorder (ADHD). The steps for psychological instrument development were followed: operationalization of the construct, theoretical analysis of the items, and search for evidence of validity. 761 people of both sexes, aged between 18 and 76 years old, with incomplete and complete higher education, participated in it. Data collection occurred electronically. A fit analysis of the IRT Three-Parameter Logistic Model was performed. The final version of the scale has 15 items and an acceptable internal consistency index (α=0.73), besides five anchor levels (-2, -1, 0, 1, and 2) that allow identifying differences in knowledge about ADHD. It is suggested that more studies using this instrument be produced, contributing to a more robust validity and, consequently, contributing to the psychoeducation of ADHD.

Keywords : attention deficit hyperactivity disorder; psychometrics; psychoeducation.
